The invention relates generally to tools-used by linemen, andmore.particularlytoqa tool to assist a telephone lin'emanin installing 'a,hook to support an insulator.

h eral. ob ect. of t i ren niisjto' 'p o.-. e. a novel i001 f cil ti he'sta la'tion f. insulator hooks, which is adapted .to be used with othertools, ordinarilycarried by a telephone, lineman, and which permitsthemto installlthe hooks quickly and with a minimum o-f efiprh.

Another object is to provide a novel tool ofthe foregoing character,which maybe easily .placed, on a hook and removed therefrom, andgwhichengages the hook without marring the t ieads: thereon.

A further object; is to .providea noveltool of; the foregoing characterwhich so .-interfits .withthe hook that, whenend pressure isplaced m1.the tool to force the hook inwandly,the-$0014 held in axial .alignmentwith the hook- Other i ts {and a van a e w l-b come. ap.-, parent fromthe following descriptiqnt takonzrini connection with t e acc mpanyin dawi s; 3. which:

In installing a telephone in a building such as a house, the wire whichextends from a nearby pole is secured to an insulator usually mounted onthe side of the house. The insulator is so secured to the structure ofthe house that it will carry the physical stress of supporting the wire.Thus, in Fig. 1, I have shown a portion of a house at It) with aninsulator H mounted thereon. The insulator is usually made of ceramicmaterial or the like and preferably has a spoollike form. To support theinsulator, a hook, indicated generally at [2, is provided.

The hook I2 is of standard form and comprises a shank l3 provided at itsend with woodscrew threads l4 adapted to be screwed into the structureof the building. Intermediate the ends 2 of thehook anoffset-portion'lfi. is vprovided and the outersend. ofthezxhookindicated-at 11-6, is ntiataan angle o-the shank to extend upwardlyandn'outwardiyiifrom the-building structure: to receive the insulator il. The-endportionlfi is threadedas 813 1112 to receive a nut 1'82adapted to hold theinsulator :H ;on:.ithe hook. It vis commonpraoticeamong; telephonelinemen to' install such a ;'hook by:- firstydriving; astarting:- hole in: the building structure into which the 1 threaded:end. M. of the thookwis inserted." Such-starting hole isfrequentlyformed .merely by: driving. a spike: a short distanceinto'.thebuilding structure and then removing it.

In screwing the hook into the buildingafter inserting it into thestarting hole; considerable torque is required-and the lineman hasdifficulty in applying such torque i f he merelyattemptsto--do so bymeans-ofpliersor an ordinary-wrench. However, a telephone linemanusually carries, as part of his kit', a carpenters brace, so that'if atool-adapted--tobe-utilized with such a brace were-provided; theinsertion of the hook would be greatlyffacilitated; i The-presentinvention-provides-such, a tool:

shown inf'thezdrawings, the preferred embodiment of thetool comprises-ashank 20 provided atone end with-a taperingsquared portion 2l"0f usualform to .fit. into 'a carpenters brace; 0111 the other endof the shank.Zllithere is provided means for gripping-the hook and holding itinaccurate axial; alignmentwith the brace. To.th'is,.en'd, suchmeanscomprises a pair of jaws 2'2' spaced apart sufficiently to embracethe hook and preferably of sufficient width and length, as indicated inFig. 4, to completely. embrace the offset portion l5 of the hook.Extending generally laterally from the jaws and in proper angularrelation is a tubular extension 23 adapted to receive the portion l6 ofthe hook. The tubular extension 23 is of substantial length and extendsfor a substantial distance laterally from the jaws so that adequatetorque may be applied to the hook without chance of damaging the threadsI! thereon. The bore of the tubular extension 23 extends through thespace between the jaws 22 so that the tool may be placed on the hookmerely by sliding it laterally over the end portion is thereof.

As heretofore mentioned, some end pressure must be applied to the hookby the tool when inserting it into the starting hole in the buildingstructure. Such end pressure is necessary in order to cause the threadsM to bite into the 3 wood of the building. The particular angularrelationship of the portion [6 of the hook to the shank 12 would tend tocause the tool to shift laterally on the hook, when end pressure isapplied, and thus would tend to cause the tool to become misaligned withthe hook. To prevent such action from occurring, I so form the tubularextension 23 as to engage the offset portion l of the hook when theshank 2B of the tool and the shank 12 of the hook are aligned. Thus, thetubular extension 23 has a portion 24 extending between the jaws 22 toengage the bend of the oifset portion l5 when the shank 20 of the tooland the shank l2 of the hook are in axial alignment. Consequently, whenend pressure is applied to the tool, it will tend to shift laterally,

because of the angular position of the tubular extension 23, until theportion 24 engages the offset portion I5, and at such time properalign-' ment of the tool and hook are provided.

From the foregoing description, it will be apparent that I have provideda novel tool to facilitate the work by a telephone lineman of installingan insulator hook. With a tool of the character herein disclosed, suchhooks may be quickly installed with a minimum of' effort. The tool iseasily placed on and removed from the hook and engages it in such amanner that the threads thereon wil1 not become marred and so thattorque may readily be applied to the hook to screw it into the buildingstructure. The tool interfits with the hook in such a way that, when endpressure is applied to the tool, it shifts to an aligned position withthe hook.

I claim:

1. A tool for inserting a. hook formed with a shank portion, a stemportion extending at an obtuse angle to said shank portion and a bentoffset portion between said shank and stem portions, the bend of saidoffset portion lying in the plane passing through the shank and stemportions, said tool comprising a, shank, a pair of parallel spaced jawsextending from the end of the shank, the spacing of said jaws beingsuificient to embrace the offset portion of said hook, and a tubularextension projecting generally laterally from the jaws and atsubstantially the same angle to the jaws as that between the shank andstem portions of the hook and adapted to receive the stem of the hook,said tubular extension having a portion projecting between the jaws toengage in the bend of the ofiset portion of the hook, whereby the shankof the hook and the shank of the tool become axially aligned uponapplication of end pressure to the shank of the tool and toward thehook.

2. A tool for inserting a hook having a. shank portion, a stem portionextending at an obtuse angle to said shank portion and a bent portionconnecting said shank and stem portions, said bent portion lying in theplane of said shank and stem portions, comprising a shank, a pair ofspaced jaws extending from the end of the shank and adapted to embracethe bent portion of the hook, and a tubular extension projectinglaterally from the jaws at substantially the same angle to the jaws asthat between the shank and stem portions of the hook, the space betweenthe jaws adjacent the tubular extension forming a continuation of thebore of said extension whereby the tool may be readily placed on thehook by sliding it laterally over the stem of the hook, the angularrelation of the tubular extension to the jaws causing the bent portionof the hook to shift into engagement with the inner end of the tubularportion when end pressure toward the hook is applied to the shank of thetool.

3. A tool for inserting a hook comprising a threaded shank portion, astem portion extending at an obtuse angle to said shank portion, and abent portion lying in the plane defined by said shank and stem portions,said toolcomprising a shank, a pair of spaced jaws extending from oneend of the shank of the tool and adapted to embrace said bent portion ofthe hook, and a tubular extension projecting laterally at said end ofthe shank of the tool at the same angle to the jaws as that between theshank and stem portions of the hook to receive the stem portion of thehook, said tubular extension having a portion extending between the jawsto engage in said bent portion and thereby prevent the tool fromshifting laterally of the hook when end pressure toward the hook isapplied to the shank of the tool, said end pressure forcing the shankportion of the hook into centered relation with said shank of the toolby virtue of the angular relation between said extension and the shankof the tool.
